摘　　要：以LED矩形阵列光源为基础,根据非成像光学理论,分别建立图像采集系统中间接照明光源的设计模型,分析了光源结构参数对光照质量的影响规律,利用遗传算法优化获得了两种照明方法的最佳结构参数,并利用光的漫反射对光源进行二次设计,以目标面光照均匀性为目标,获取最佳反射曲面,在光学设计软件中验证了设计方法的正确性。Based on rectangular array LED light source,according to the theory of nonimaging optics,respectively,design model for indirect lighting light source,in image acquisition system is established.Influence law of light source structure parameters on quality of the light is analyzed,genetic algorithm is used to optimize win the best structural parameters of two methods of lighting,and use the diffuse reflection of light for the secondary design of light source,aiming at target surface illumination uniformity,obtain the best reflective surface,the correctness of the design method is verified by optical design software.
